Enjoy a refreshing night of sleep with the SERTA THERMAGEL Memory Foam Pillow with AQUACOOL Surface Infusion Technology. Designed with advanced THERMAGEL memory foam technology, this pillow keeps you cool by working to transfer heat away from the body. It also features an AQUACOOL gel surface infusion on one side of the memory foam that provides increased temperature regulation, a cool-to-the-touch feel, and your choice of temperatures when going to sleep (depending on which side you choose). The machine washable cover features one side that is cool to the touch to offer even more customizable cooling options. Supportive memory foam enhances comfort, adapting to the contours of the head and neck for superior pressure relief. Not just sorta comfortable. SERTA comfortable.
